Description Trawling which is the highest contributor to the
marine fishery in India has undergone sea change as
a fishing technique and fishing pattern. During
recent years, the reduction of catch per unit effort
from existing fishing grounds led to various modifications
in trawl net design and trawling operations,
which has resulted in increase in fish production.
Impacts of trawling in Indian waters have been
monitored by various agencies during last 25 years.
Although there are a good number of articles in peer
reviewed journals, a huge quantity of useful information
still lies in the form of reports and grey
literature which is not easily available to the researchers.
This paper attempts to compile information
available from various research papers, reports
and presentations in seminars and symposia, to serve
as an updated guide for trawl impact studies. The
information are categorized as (i) impact on the
ecosystem, (ii) impact on fishery and (iii) impact on
biodiversity. The paper also analysis recent trends in
trawling like pelagic and high speed trawling in
Indian waters, taking up an example from the trawl
fishing off Karnataka, south west coast of India. It
was seen that after the introduction of high speed
pelagic trawling, some of the areas which were
unsuitable for trawling, have also been brought
under exploitation. The utility of log book data in
resource conservation studies and the need for
incorporating spatial studies in trawling impact
assessment in the context of ecosystem stability and
fishery sustainability are also discussed.
